MCP servers fail to connect with `npx` on Windows #40

naif0s · 2024-11-25T21:00:09Z

I am on Windows with the latest desktop version, I have enabled developer mode and I am in Europe

sean-lynch · 2024-11-25T21:19:40Z

Can you share your %APPDATA%\Claude\claude_desktop_config.json? (In case this doesn't make sense, I'm referring to step 2 in the Windows quickstart guide here: https://modelcontextprotocol.io/quickstart#installation)

naif0s · 2024-11-25T21:23:52Z

jwross24 · 2024-11-25T21:30:06Z

The docs are a bit confusing, and I had a similar issue. You should add the individual MCP servers under the mcpServers key in the JSON like so.

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        ...
      ]
    },
    "memory": {
      "command": "npx",
      "args": [...]
    }
  }
}

They should then show up correctly in the Developer config.

naif0s · 2024-11-25T21:35:46Z

Thank you, it works! Now, how do I integrate Github?

jwross24 · 2024-11-25T21:37:55Z

You should use the github config that you had before, instead of the filesystem and memory configs that I have. You can add it as another key after filesystem and memory, though those configs won't work exactly as I have written since I omitted the args key for brevity.

You can try:

{
  "mcpServers": {
    "github": {
      "command": "npx",
      "args": ["-y",  "@modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "<YOUR_TOKEN>"
      }
    }
  }
}

naif0s · 2024-11-25T21:48:14Z

OK Thanks, it's super cool for your help. But well... it's not working. I entered the key correctly but when I ask Claude, for example to create an issue, it won't do it

jspahrsummers · 2024-11-25T22:35:57Z

Are you able to get the GitHub server working with the MCP Inspector? That will help narrow down whether this is a desktop app issue, or a problem with the server setup.

geelen · 2024-11-26T00:46:06Z

I've got almost the exact same situation. I have two servers configured:

{
  "mcpServers": {
    "sqlite": {
      "command": "uvx",
      "args": ["mcp-server-sqlite", "--db-path", "/Users/glen/src/experiments/claude-local-sqlite"]
    },
    "brave_search": {
      "command": "npx",
      "args": ["@modelcontextprotocol/server-brave-search"],
      "env": {
        "BRAVE_API_KEY": "<redacted>"
      }
    }
  }
}

My debug log looks fine:

Settings looks fine:

But no 🔌 icon in the chat window:

And a flat refusal to do anything with the connections:

geelen · 2024-11-26T00:53:41Z

Update: just tried on my windows machine, and got the exact same result. Is it possible this is geoblocked in Australia?

ProRedCat · 2024-11-26T01:02:45Z

Same issue here, there is no 🔌, I do have the filesystem server running but I get a message in Claude Desktop of it failing to attach to the MCP server.

To add more context based on what geelen said, I am from New Zealand and running on Windows so could be georestrictions, or it could be some device setup.

Having issues running MCPInspector as well so debugging is a bit difficult

ProRedCat · 2024-11-26T02:25:01Z

Update on my end, I switched over to a MacBook as there seemed to be some issues with running this on Windows see: modelcontextprotocol/inspector#76

For the filesystem server it is now working as well as the Github server. The region locked theory is wrong, it's just device configuration/OS support.

For the SQLite and Brave Search the issues #37 #42 may be helpful for the others in this thread as there seems to be some issues with pathing sometimes - though I am still facing issues on Windows.

geelen · 2024-11-26T02:57:42Z

You're quite right. I had a typo in the path to my DB! That was crashing things, even stopping me from adding other tools.

Sunwood-ai-labs · 2024-11-26T10:26:53Z

I'm also experiencing issues with the filesystem server on Windows. Here's my configuration:

{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "C:\\Users\\Username\\Desktop"
      ]
    }
  }
}

timurkhakhalev · 2024-11-26T11:22:58Z

Same behavior on Windows 11 and Mac OS. Claude desktop 0.71.1 version on both devices.

Da1sypetals · 2024-11-26T11:58:42Z

I'm also experiencing issues with the filesystem server on Windows. Here's my configuration:

Experiencing similar issues on Mac OS using Claude Desktop 0.71.1.

mcgraf · 2024-11-26T12:02:42Z

I am having the same issue on Windows 10 with latest Claude Desktop

RELMYMathieu · 2024-11-26T13:59:32Z

Same issue, log file attached:

mike-luabase · 2024-11-26T14:01:07Z

@mckaywrigley what does your config file look like?

code ~/Library/Application\ Support/Claude/claude_desktop_config.json

thenameless7741 · 2024-11-26T14:12:30Z

Here's what works for me (mac):

TL;DR Try using an absolute path and specify the latest Python version in claude_desktop_config.json when configuring uvx.

Detailed version:

I followed the sqlite instructions but ran into a "Could not connect to MCP server sqlite" error.
After enabling developer mode, i checked to the log file through Developer (menu bar) → Open MCP Log File (mcp.log) and found this error "Could not start MCP server sqlite: Error: spawn uvx ENOENT".

The fix was to use an absolute path in claude_desktop_config.json, e.g.

> which uvx
/usr/local/Homebrew/bin/uvx

After restarting Claude, the "Attach from MCP" button still wasn't appearing next to "Upload files" button.
Checking mcp-server-sqlite.log (in the same directory as mcp.log), I saw this error:

No solution found when resolving tool dependencies:
Because the current Python version (3.9.1) does not satisfy Python>=3.10
(omitted)

Since i have a newer Python installed (via miniconda), I resolved this by passing an extra --python arg to uvx, using the absolute path to python binary.

My full JSON config file:

{
  "mcpServers": {
    "sqlite": {
      "command": "/usr/local/Homebrew/bin/uvx",
      "args": [
        "--python",
        "/usr/local/Homebrew/Caskroom/miniconda/base/bin/python3",
        "mcp-server-sqlite",
        "--db-path",
        "/Users/<user>/test.db"
      ]
    }
  }
}

jspahrsummers · 2024-11-26T14:30:50Z

@thenameless7741 Just to check, are you on an Intel Mac? /usr/local/Homebrew isn't searched as part of the path right now, but that's something we could fix.

jspahrsummers · 2024-11-26T14:34:46Z

Sorry folks, and thanks for your patience! For npx calls in particular, we believe there's an issue with how Claude Desktop is launching subprocesses on Windows, which modelcontextprotocol/typescript-sdk#68 (once integrated) should hopefully fix. 🤞

As a workaround, you should be able to npm install -g the MCP servers you care about, and use node to invoke them directly (instead of npx).

thenameless7741 · 2024-11-26T14:58:12Z

@jspahrsummers I'm still using the old Homebrew setup on my M1 and haven't migrated over to the /opt directory yet. I suspect there are a few others out there in the same boat as me.

oscarcalvo · 2024-11-26T15:42:19Z

@jspahrsummers FYI, I'm using Windows. The memory server is installed globally, but it’s still not working. The closest I’ve gotten is with this config, which starts the server, but after 1 minute, Claude shows the same error: 'Couldn't attach...'

"mcpServers": {
"memory": {
"command": "mcp-server-memory",
"args": []
}
}

rkaradas · 2024-11-26T15:59:01Z

@oscarcalvo As @jspahrsummers mentioned, you have to use node directly, like this

{
	"mcpServers" : {
		"filesystem": {
			"command": "node",
			"args": [
			"C:\\Program Files\\nodejs\\node_modules\\@modelcontextprotocol\\server-filesystem\\dist\\index.js", 
			"C:\\"
			]
		}
	}
}

@rkaradas You are right, thanks

timur-khakhalev · 2024-11-26T16:45:57Z

Any ways to access mcp-server inside WSL?

I've tried this but no luck:

"command": "wsl",
            "args":
            [
                "bash",
                "-ic",
                "node /home/timur/dev/personal/mcp/mcp-server-jina/build/index.js"
            ],

"command": "node",
            "args":
            [
                "\\wsl.localhost\\Ubuntu-22\\home\\timur\\dev\\personal\\mcp\\mcp-server-jina\\build\\index.js"

Since it's the only server you have configured, here's what I'd do (i've just tested this from scratch).

Rename your claude_desktop_config.json file to claude_desktop_config.old
Open PowerShell, and download the script from earlier to a folder
Run Set-ExecutionPolicy Bypass -Scope Process in powershell
Run .\mcp-install.ps1 @modelcontextprotocol/server-filesystem
Edit your claude_desktop_config.json folder and add the folders you want to use (don't forget to add a comma after the first argument).
Start Claude and enjoy.

If that still doesn't work, paste the content of the Logs folder in here.

Sure, I wouldn't run that from system32.

From there I would:

cd ~ -> (takes you to home folder)
curl -o mcp-install.ps1 https://llmindset.co.uk/scripts/mcp-install.ps1 -> (downloads and save the install script to your home folder)
.\mcp-install.ps1 @modelcontextprotocol/server-filesystem -> (installs the server)

Once that's done, you can then edit the claude_desktop_config file to add the folders you want to use.

[EDITED - I messed up the curl command, sorry]

Thank you for your relentless efforts trying to help :))))...btw Happy 2025~~~
I tried what you've recommended, still no luck, here's the code, not sure i've done something wrong, apprecaite any insight you might have :)

Before I ran the Pwershell Script, I made sure i'm running from system64 tho it says system32 - reason why it's saying system32 is because "On bit64 Windows The folder C:\Windows\System32\ actually holds 64-bit system files - according to ChatGPT".....
I also made sure that the "claude_desktop_config.json" has been renamed to "claude_desktop_config.old".
Here comes the screenshots.....

At this point, a new "claude_desktop_config.json" file has been created in folder C:\Users\meizh\AppData\Roaming\Claude
I opened the json file and saw this script.

I opened Claude to see this error msg

Then I overrode the json script to below... saved and relaunched Claude...

Saw this error msg.... "Could not attach to MCP server server-filesystem"

Side question - it's been a hell of a workaround trying to add one MCP to Claude, is it going to be the same for all other MCP's? I'm also looking to add the Brave Search one....

evalstate · 2024-12-31T18:13:28Z

OK - looks like its nearly there. Go in to settings, developer and click here to open the logs folder.

In there you should find a file called mcp-server-filesystem.log. Show us the contents of that.

For what it's worth, I got my server-filesystem to fail by specifying an invalid path on startup.

Side question:- once this issue is solved, you should be all set :)

here's what i have.. is it about the y arg?

evalstate · 2024-12-31T20:24:19Z

OK - so the error message makes it look like Claude is reading a claude_desktop_config.json which still has a "-y" in the args section of the Config file... so perhaps there is more than one config file.

Can you re-check what is in the claude_desktop_config.json file by opening it from here:

That will open an explorer window with the file highlighted. Right-click, open in notepad or vscode and lets have a look what's in that specific one.

Sure thing.
I clicked on "Edit Config" and was redicted to C:\Users\meizh\AppData\Roaming\Claude
I then opened "claude_desktop_config.json"
this is what i have (pretty sure i took the -y out):

evalstate · 2024-12-31T21:11:30Z

🤔.

OK. Can you go back to the logs folder, delete all the files in there, restart Claude Desktop and then see what's there? Perhaps we are looking at a stale log file with the old config in.

Claude is still giving the error message, right?

Cool. So we know that Node.js is installed and running.

The error message in the log file is saying it can't find the server-filesystem MCP Server code (which is odd because npm should have downloaded it earlier).

Let's check 2 things before going further:

Go back to powershell and run the following:

node --version

Should return v22.12.0

Then run: npm root -g

This will show us the download directory - it should come back c:\program files\nodejs\node_modules. I'm wondering if you are on a virtual desktop environment?

mchen-227 · 2024-12-31T23:50:33Z

I never "End Task” when closing out Claude, I normally just click on "File--> Exit". I tried to End Task in Task Manager this time around after updating json. Not sure if this has been an issue for everyone, but I've seen some people mention the same on YT.

Just wanted to add my solution to this without uninstalling node or using nvm on windows:

Check where your node is

PS D:\Javascript\foldername> where.exe node
C:\Users\username\AppData\Local\fnm_multishells\13228_1736585930049\node.exe

claude_desktop_config.json

{
  "mcpServers": {
    "filesystem": {
      "command": "C:\\Users\\username\\AppData\\Local\\fnm_multishells\\13228_1736585930049\\npx.cmd",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem",
        "D:\\Javascript\\foldername"
      ],
      "env": {
        "PATH": "C:\\Users\\username\\AppData\\Local\\fnm_multishells\\13228_1736585930049;%PATH%",
        "NODE_PATH": "C:\\Users\\username\\AppData\\Local\\fnm_multishells\\13228_1736585930049\\node_modules"
      }
    }
  }
}

The key is to use absolute path for npx command, then adding env PATH and NODE_PATH

Check whether there is a @modelcontextprotocol folder under c:\users\meizh\appdata\roaming\npm\node_modules. If so change the path under "args": it from "C:\\Program Files\\nodejs\\..." to c:\\users\\meizh\\AppData\\Roaming\\npm\\node_modules\\@modelcontextprotocol\\server-filesystem\\dist\\index.js.
and restart Claude

I GOT IT!!!! problem could be 3-fold

I tried globally reinstall the library in PS.... npm install -g @modelcontextprotocol/server-filesystem

For whatever reason, system is not liking the destination "C:\Users\meizh\Documents" so I recreated a new folder for Claude (tho this could very well not be the true issue but I recreated a folder anyway and updated that config.json file).

I never "End Task” when closing out Claude, I normally just click on "File--> Exit". I tried to End Task in Task Manager this time around after updating json. Not sure if this has been an issue for everyone, but I've seen some people mention the same on YT.

Thank you for your relentless help!!!! HAPPY 2025 :)

This worked for me on Windows - needed to stop the Claude.exe task in task manager and then start the app again in order for it to really read and install the packages noted in my mcp config. Simply closing the app on windows and starting a new instance is not a full restart and does not seem to trigger a fresh look at the config, so trial and error adjustments there were not reflecting readily until I tried the full claude.exe process kill in task manager. Thanks for the tip!

ctrl+q on windows does a "proper" quit, to save anyone the bother of using task manager :)

wish someone had told me that earlier too.

Sigue sucediendo lo mismo, lo solucione haciendo esto

      "args": [
        "C:\\Users\\{{user}}\\AppData\\Roaming\\npm\\node_modules\\@metamcp\\mcp-server-metamcp\\dist\\index.js",
        "-y"
      ],
